1620 disable jumbo frames

[MarkosV]

Hello,

I have a 1620-48g switch and I want jumbo frames disabled.

In the product spec it is mentioned that there is jumbo frame support.

However in the manual I cannot find anything mentioning jumbo frames and it is certainly not configurable from the web gui.

So, my question is:

Are jumbo frames enabled by default in this model and if yes, how do I disable it?

Thanks in advance to anyone who takes the time to give me an answer.

Hi ,

The jumbo frames or enabled by default . if you like to disable it , login into CLI and issue " undo jumboframe enable" on globally.  To re-enable it  issue "jumboframe enable"

Thanks for the reply,

I gave the command using the serial console CLI (no telnet on 1620s):

<1620 48port Basement>undo jumboframe enable
^
% Unrecognized command found at '^' position.

There is no xtd-cli-mode option as in other COMWARE:

<1620 48port Basement>?
User view commands:
initialize Delete the startup configuration file and reboot system
ipsetup Assign an IP address to VLAN-interface 1
password Specify password of local user
ping Ping function
quit Exit from current command view
reboot Reboot system/board/card
summary Display summary information of the device.
upgrade Upgrade the system boot file or the Boot ROM program

'en', 'sys', 'config', '_cmdline-mode on' do not work either.

How should I give the "undo jumboframe enable" command?

Thanks again

Hi,

Can you check any other show / display command in CLI ?

It seems that no cli commands (apart from the basic) can be executed in this restricted mode and elavation is not possible using the common commands as in other comware. Should I contact HPE support?
